Interior Low Plateaus Reptiles and Amphibians by Month

Rolling hills, caves and limestone streams cover the Interior Low Plateaus. Pond Sliders are the most-reported herp. American Toads and Fowler's Toads call from spring into summer. Central Ratsnakes and Common Watersnakes are the common snakes. April is the busiest month, and the Eastern Copperhead is the venomous snake here.

Peak and shoulder ratings are rough guidance, not a schedule. Weather, elevation and the year can shift any species by weeks.

Rare and protected species are left off on purpose. Look, don't take, and never handle a venomous snake.

Keep Herp Calendar free

Hi, I'm Nick. I built Herp Calendar on my own and I keep it free, with no ads. If it has helped you find a herp this season, a small tip goes straight into the hosting and the data work. Only if you can spare it. Either way, I'm glad you're here.
